ABSTRACT:
The burst signal existing on the back porch of the composite color signal is brought to a predetermined normalized value with the aid of an amplitude control loop. In order to further increase the gain of a multiplier provided for in the control loop the multiplier is preceded by a premultiplier of simple design, whose multiplication factor is capable of being switched over in powers of two. A multiplication factor setting signal, is converted via a code converter into two control signals, with the first control signal setting the multiplication factor of the premultiplier, and with the second control signal setting the multiplication factor of the multiplier.
